I've just had to go through a process of explaining to colleagues how to position equipment so that wheelchair users can retain their independence, which, along with dignity is lost when people become paraplegic or quadriplegic. There seemed to be a lack of imagination about how to deal with the with - problem "oh, there will be someone to help", was the first response. This man, after his own wheelchair was "left behind on a flight", and finding that the airport didn't have a basic wheelchair that he could operate himself, opted to maintain his independence instead being strapped into a wheelchair and relying on someone else to wheel it through the airport, something that he felt was less dignified than getting there himself. Kudos to him for dealing with the airline and airport's service failures himself. Hopefully the publicity will improve service standards.
